onstat -g act Active Threads

The onstat -g act command displays a list of the currently active (running) threads. The output is sorted by thread ID.

Running threads:

Output Description

Heading	Description	Format	See Also
tid	The thread id incrementally assigned by OnLine.	Dec	onstat -g ath
tcb	The in-memory address of the thread control block.	Hex
rstcb	The in-memory address of the RSAM thread control block.	Hex
prty	The internal priority of the thread.	Dec
status	The status of the thread.	Str
vp-class	The class of VP on which the thread is running.	Str	onstat -g sch
name	The name of the thread.	Str

Notes

There are never more threads running than there are virtual processors (VP).

A thread priority can range from 1 (lowest) to 4 (highest) with a default priority of 2. Priorities are assigned internally by the server and are not tunable.

Monitoring and Tuning

The onstat -g act command is a quick place to identify if certain threads are actually running such as the KAIO thread, the poll and listener threads, and other threads as set in the configuration file.
